TRACTOR nnivn WHEEL.

Application iled May 16, 1922.

To all whom l? may concern.'

Be it known that l, FREDERICK E. SHIM- oNnK, a citizen et the Dominion ot Canada, residing at St. .lea-n Baptiste, in the county of Provencher and Province ot ldanitoba7 Canada, have invented certain new and useful lmprovements in Tractor Drive Vheels, of which the following is ak specification.

The subject matter forming this application relates to tractor drive wheel construction adapted for use on conventional types of tractors. j

rlhe object ot my invention is to provide a drive wheel having a plurality ot gripping cleats disposed on the periphery thereof, which may be withdrawn trom the periphery of the wheel when travelling over roads.

Among other aims and objects ot my invention may be cited the provision o a traction drive wheel ot the character described with a view to compactness and durability.

rllhese and other objects l accomplish by means of such structure and relative arrangement of parts as will readily appear by a perusal of the following description the descriptive matter being supplemented by the accompanying schematic illustrations, wherein:

Figure 1 is a side elevation of a tractor drive wheel constructed in accordance with my present invention.

Figure 2 is a medial vertical. section of the tractor drive wheel shown in Figure 1.

Figure 3 is an enlarged fragmentary detail illustrating the connection ol the spokes andcleat standards oit the drive wheel.

Figure 4 is an enlarged medial vertical section further illustrating the connection of the spokes and cleat, supporting standards of the drive wheel..

Figure 5 is an elevation of one of the cleats and cleat standards incorporated in my present invention.

Figure 6 is a plan of the cleat as it would appear from the periphery of the wheel.

Figure 7 is a fragmentary detail of the hub cap incorporated in my present invention and f Figure 8 is a detail of the lever employed to extend or withdraw the adjustable cleats incorporated in my tractor drive wheel construction.

Referring to the drawings in detail, wherein like numerals of reference designate corresponding parts, the numeral 9 riesig-- Serial No. 561,481.

natos the rim ofthe wheel, 10 the outer periphery thereof and 11 the inner periphery thereof. The tractor drive wheel is carried by the rear axle 12 of the tractor through the medium 'of the hubs 13 and 14 .and the plurality ot spokes 15 and 16, which are seated in the hubs 13 and 14 and have their opposite extremities substantially seated in the rim 9 of the tractor drive wheel, best shown in Figure 2. The numeral 17 desig nates a bushing positioned about the axle 12 intermediate the hubs 13 and 14. This bushing keeps the said hubs in proper spaced relation.

The numeral 18 designates an adjustable collar rotatably mounted on the bushing 17. A plurality ot apertures 19 are drilled transversely in the said collar7 while a plurality ot apertures 2O are drilled in the hub 14 in congruent spaced yrelation thereto. The numerals 21 designate a plurality ot countersunk apertures disposed in the inner tace ot the hub 13. The hub plate 22 has a plurality of rods 23 extending therefrom, best shown in Figures 2 and 7. The said rods extend through the apertures 2O and 19 and seat in the countersunk apertures 21. Through the medium ot the said rods, it will be discerned that the adjustable collar 18 may be held in the required position. The hub plate 22 is held in position by the cap screw 24.

A plurality ot cleat standards, generally designated by the numerals 25, have their inner terminals tiattened as at 26 and have the apertures 27 drilled therein. Bolts 28 extend through the adjustable collar 18 and through the said apertures 27. rlhe op posite extremity ot each standard is bi furcated and has mounted on the outer extremity thereof a gripping cleat 29. The gripping cleats 29 are housed in the casings 30 termed on the said periphery 11.

W'hen it is desired to withdraw the cleats 29 from the periphery 10 of the rim 9, the cap screw 24 is removed and the hub plate and the rods 23 are withdrawn. It is obvious that the adjustable head 28 may be rotated onthe bushing 17. The terminal 31 ot the lever 32 is then inserted in one of the apertures 33 formed in the adjustable collar 18 intermediate the cleat standards 25. Through the medium of the lever 32, the adjustable head 18 is adjusted as required and the adjustable cleats 29 will be withdrawn from the periphery 10 of the rim 9..L

Iii Figure 3, I have shown the position ot the standards 25 as they would appear when the cleats 29 are withdrawn from the periphery l0 of the tractor drive wheel. When in this adjusted position, the rods 23 are inserted in the apertures. and l9and the countersunk apertures 2l, and the cap screw 24% positioned in the outer extremity of the axle l2, as diagraininatioally illustrated. The adjustable head is turned the distance oit' space between the apertures 20.

A perusal ot' the foregoing description will substantiate that I have provided a very useful and durable tractor drive wheel. Since probably the best results may be obtained :troni the invention as disclosed, the oon` struction ot the saine may well be 'tollowed, but within the scope of the invention as detiued by the appended claim, minor changes may be made. y

Whaty I claim as new is:l n

In combination with a supporting axle, a tractor drive wheel comprising dual spaced hubs,` a bushingr intermediate said hubs, a collar rotatably carried on said bushing, a pluralitv of spokes carried by said dual hubs surnam-ting a riin, a plurality ot standards carried by said headl` gripping Cleats disposed on the outer extremities of said standards adapted to extend through said rim, housings for said Cleats on the inner pe* riphery of the rim` a set ot oppositely registeringopenings in said hubs and said adjustable collar` a hub plate provided with a set ot locking' pins adapted to be seated in said openings when said Collar is turned o extend or withdraw said Cleats troni said rin'i and a ineans ot lookingsaid hub plate in fixed position.

In testiinonv whereof` I affix inv sienature in the presence ot two witnesses.
